IMPROVEMENT IN TOBACCO-PIPE STEMS.

Specification formin g part of Letters Patent No. 43.907, dated August 23,1864.

,To all whom it may concern:

\ tion of the same,-reference being had to the accompanying drawings, in which Figure 1 is a perspective view of a pipe with my improved stem. Fig. 2 is a longitudinal section of my stem, showing the internal construction of the same. I

The nature of my invention consists in such a construction of the stem of a smoking-pipe as will secure the passage of the smoke withoutits coming in contact with the saliva, which runs down the tube toa point as near the outer orifice of the tube as it is practicable to take it.

That others may understand the construction and operation of my invention, I will describe it more particularly.

A is the pipe. B is the outer shell of the stem. 0 is the inner or smoke tube. D is the mouth-piece. E is the space between the smoke-tube and the outer shell, B.

It is well known that the saliva from the mouth running down the tube of the pipestem renders the smoke strong and offensive, and various devices have been invented for the purpose of separating the smoke from the moisture spoken of above. None of these have been fully successful, for the reason that the receptacle prepared for the reception of. the saliva and nicotine has always been'placed near to the bowl of the pipe, and as a consequence the smoke traverses a moist tube for the greater part of the length of its passage. This difficulty is obviated by the device herewith presented.

The outer shell of the stem may be constructed of wood or any othersuitable material. It is a hollow cylinder of sufficient internal capacity to contain the smoke-tube C, and secure a clear space all around the latter between its outer surface and the inner surface of B. The smoke-tube C may be made of metal or any convenient and suitable material, and should extend from the lower end of B to a point as near the orifice of the mouthpiece as practicable.

The operation of my invention is'as follows: Any saliva which may run down through the mouthpiece will not come in contact with the smoke-tube, but will run down the space E inside of B, which forms a receptacle for the saliva, into which it is collected and retained until removed. The efiect of this arrangement is to convey the smoke to within a very short distance of the lips in a perfectly-dry condition, uncontaminated by contact with the saliva, and therefore/much more agreeable and satisfactory to the taste.

The smoke-tube C and the outer shell B may be both made at one operation by boring out the space E with a suitable tool, and there will then be no joint at the lower end between two tubes; or they may be put together as represented, or in any other suitable manner.

I am aware that pipe-stems have been made with two tubes bored side by side, and only joining when very near the orifice of the mouth-piece, and that these tubes are designed to accomplish the same result that mine ac complishes; but it is obvious that inasmuch as the two tubes in the case referred to are connected together at thepoint of their junction the saliva cannotbe excluded from the smoketube 'as effectually as by my arrangement, where there is no connection between the smoke-tube and the outer shell, and the saliva cannot by any possibility enter the smoke.

tube.

Havingdescribed, my invention, what I claim as new, and desire to secure by Letters D. D. FOLEY.
